"WASHINGTON - Fifteen U.S. states sued the National Highway Traffic Safety Administration (NHTSA) on Tuesday after it agreed last month under then-President Donald Trump to an auto industry request to delay the start of dramatically higher penalties for companies that fail to meet fuel efficiency requirements.

The state attorneys general, including from California and New York, filed suit in the U.S. Court of Appeals for the Second Circuit over the decision announced in the final days of the Trump administration.

NHTSA said last month it expected the final rule to cut future burdens on industry by up to $1 billion annually."
